아이슬란드 해역의 해양생물기원 DMSP의 분포와 대기 DMS에 대한 기여

Master Dimethylsulfoniopropionate (DMSP) is a ubiquitous phytoplankton metabolie and the main precursor of dimethylsulfide (DMS) which is considered as one of climate-active gas in the oceans’s surface. In addition, it is a major source of nature flux of sulfur compound to the atmosphere. I particip...
